Dear Mark,

Do you see a change in unit cell dimensions? I would be interested to know
about MFID v resolution for your 2 data sets?  Does a reduction in
mobility/thermal motion lead to improved scattering?  Whilst I've seen
publications on protein models refined against data sets collected at different
temperatures I don't recall seeing a detailed comparision of the actual data.
Do you know of any relevant papers on the subject?
